To all 'whom it may conce-m:

Be it known that I, ALBERT Lmsnt., a citizen of the United States of America, re

siding in lewark, inthe county of Essex and State of New Jersey, have invented certain new and useful `Improvements 1n Machines for Doubling'Fabrics, of which.

the following is a specification.

This invention relates to an improved machine for doubling fabrics by which two different fabrics, such as leather, imitation leather, mohair and the like, can-be united with a backing layer of Acotton or other fabric by means of a waterproof cement so as to-be capable of resisting wear and the influence of the. atmosphere; and for this purpose the invention consists of a inachine.

for doubling fabrics which comprises. a vpair of heated rolls, means for feedingtvvo separate fabrics to and over said rolls, 'uprightabutments near each end of the heatedrolls, an inclined adjustable doctor arranged adjacent to one of the heated rolls, and adjustable Scrapers arranged at the under-side of the rolls and held in contact therewith for removing.l any adhering cement from the surface of said rolls. v

The'invention consists further of certain details of construction, such as the suspen sion ofthe Scrapers and the adjustment relatively to the heated rolls, and other details of construction, 'which will' be fully described hereinafter 'and finally pointed out in'theclaims.

In the accompanying drawings, Figure 1.

represents a sideelevation-of my improved f machine for doubling fabrics, Fig. 2 is a vertical longitudinalsection ofthe sameon line. 2, 2, Fig. 3, and Fig.'3 is. a planview of the improved machine.V j

Similar letters of reference' indicate cor.

responding parts throughout the-figures,

Referringto-the drawings,- a, al are" two tubular 'rolls which are heatedby meansof live steam admitted to theinterior .of the rolls by steam supply-pipes?) connected withl one end of the 'rolls and'carried oi suitable exhaust-pipes 1 at the same-end. 'The `heated roll a is supported in stationary bearings ofa sup orting 'frame f, 'while the heated roll a?. 1s SUPPOrted Yin` s of horizontally adj-ustahleslide-re'sts 1i which. are guided on the frmef, so that the roll' al. cui be adjustednlor Ito-or away from the stationary roll a for providing for.'l

theA different thicknesses of thefabricsto be united. The' adjustment of the' movable roll a? is accomplished ley-means of screws d1 opposite direction toy veach other from a, driving shaft s, Awhich is supported in suitable bearings in the side-standards of the frame f blow the rolls, and intermediate driving gear-wheels g, g5 andgear-wheels l g2, g3 on the rolls a, a?. .The two layers of fabric to be united are' wound up on reels the shafts of which v are supported in bracket-bearings e, el at opposite ends of the frame f and conducted over suitable guide-rods e2, 6 3 and adjustable tension-rolls e4, e5 to the' heated rolls a, 1,1 and then be` tween the same in downward direction over.

a guide-roller e to a suitable conveyer (not shown) by which .the doubled fabrics, after they are united by the lrolls a, al, are `con` rolls c4, e are adjustable by means or sliderests e7, e8 which .are acted upon by screws e having hand-wheels elo so asV to apply. a.

Aducted off. The bearings of the tensionregulated tension to both layers of fabric.'

Nearthe ends of the heated rolls a, a1.' are located vertical' abutment-s 7i, the lower ends .l

of which extend by arc-shaped tapering portions lIt" into the angular space between the irolls, the arc-shaped portions being arranged The close to the surface of the rolls. ments l1. are suspended by hangery rods k2 and screw'and jam `nuts k3 'from a trans"- verse yoke'y havingA yertical endlportions which are attached tothe side-standards of the frame' f," the .top-portion., being provided with Slots lagfor perm-ating the lateral ad j ustment of the hangerlevers kz ofthe abut` ments over the. rolls, either closer together waterproofcement that is supplied tothe lfabrics in thev trough' formed between one of the fabricsI passing over the roll a1, tl1ev lower portions 'of the abutments h andan .inclined doctor which is-"supported, ona

transverse'bar 1 .that isA connected by inclined screwosts i2 and. 4screw-nuts j! to an ar brac etsz'ifattached to the, inner `oriaway from each other,l according ;to the width' of 'the fabrics to bei-doubled. .-The abutments li., h? serve to hold 'the liquefiedv sidesgof 'the abutments', as shown clearly in Vio Fig. 2. The ends of the bar l and the ends ,to the fabrics in heated and liquid condition Vso as to be spread luniformly over the surface of the ingoing fabrics, and is then firmly united with the face-fabric and its backing fabric by the pressure exerted thereon during their passage between the heated rolls, the two layers, after being doubledup or united, being then conducted uit below the rolls by passing over the roller e* at the lower part of the .frame f'.

Below the rolls a, al and in contact with the lower circumference of the same are arranged scrapers Z, Z1 which extend across the `full 'length of the rolls, said AScrapers being held in close contact with the surface of the heated rolls so as to remove any traces of cement that should be' pressed through m1- nute openings or the meshes of the fabric,

onto the surface of the same, or that portion of the cement that should run over the edges of the fabric passing over the roll a1, so that the surface of the rolls is kept absolutely cleared of even the slightest traces of cement and thereby 'the surface of the doubled-up fabric kept perfectly clear vof cement. The Scrapers Z, Zl are supported on two pairs of hangers Z2 that are pivotally united at their upper ends and suspended from the vertical portions of the yoke y and riveted or otherwise attached at their lower ends to the extreme ends of the Scrapers Z. For preventing the bending of the Scrapers midway between their ends and holding them in contact with-the heated rolls throughout their length, supporting platesl n are employed which press on the underside of the Scrapers andwhich are adjustably supported bymeans of inclined screwposts n1 and screw-nuts ns en inclined brackets n2, the lower parts of said brackets being supported Yon angular bars n4 extending transversely between the upright side-standards of the frame f, as shown in Fig. 2. By

vadjusting the threaded posts n1 of the supporting plates fn. slightly higher or lower on the brackets a2, the middle portion of the Scrapers can be accurately adjusted to the lower surface of the heated rolls. The cement that is removed-by the Scrapers from the surface ofthe rolls is collected in a suitlable receptacle (not shown) 4at the lower part of the frame and returned from time to maaien time to the trough-shaped space between the trough-shaped space, which latter acts in the nature of a hopper for supplying the waterp proof cement to the fabrics to be doubled or united.

Any suitable fabrics may' be doubled by sure is exerted on thel fabrics as they are `passing through the rolls, they are uniformly doubled and at the same time dried to a considerable extent, so that no further artificial drying is necessary. The properly backed and doubled fabrics'are wound up on a reel and ready for immediate shipment and use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. A machine for doubling-fabrics, comprising a pair of rotatory heated rolls, means for guiding two layers of fabric from opposite sides to and over said rolls, upright abutments at opposite ends of said rolls, the lower ends of which extend into the ves space between said rolls, means for suspending said abutments, and .an inclined doctor supported on said abutments in proximity to one of said rolls. l

2.l A machine for doubling fabrics, com: prising a pair of rotatory heated rolls, means for guiding two layers of fabrics from opposite sides to and over said heated rolls, upright abutments at the ends of saidheated rolls, whereof the lower ends extend into the space between said rolls, means for adjusting said abutments to the rolls,an inclined doctorsupported on said abutments in proximity to one of said heated rolls, and means for adjusting said doctor relatively to said heated roll.
